JOHN DANIEL CAMPBELL, OF LEESBURG, IDAHO.

TOOL FOR MINERS USE.

SPECIFICATION forming part of Letters Patent No. 593,459, dated November 9, 1897.

Application filed November 24, 1896. Serial No. 613,318. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN DANIEL CAMP- BELL, of Leesburg, in the county of Lemhi and State of Idaho, have invented a new and Improved Tool for Miners Use, of which the following is a full, clear, and exact description.

The object of my invention is to provide a tool for miners use which tool will embrace a candle-holder, a powder-knife, a fuse-cut-- ter, a fuse-splitter, a cap-crimper, and devices for securing the tool in a beam or suspending the said tool from any convenient support.

A further object of the invention is to so combine all of the articles above mentioned in one tool that the said tool will be compact and capable of ready manipulation, and whereby each and every portion of the tool may be brought into action, the candle remaining upright meanwhile.

A further object of the invention is to so construct the cutters that they may be readily removed and sharpened.

Another object of the invention is to so construct the cutters that they will make a clean out without danger of changing the shape of the fuse.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved Fig. 2 is a plan View of the tool. Fig. 3 is a transverse section taken on the line 3 3 of Fig. 2. Fig. 4 is a detail side view showing the fuse-cutting knives, and Fig. 5 is an enlarged detail section on line 5 5 of Fig. 4.

The body of the tool is in the nature of a pair of pliers embracing two opposing jaws 10 and 11, each of which is provided with a handle, the handles being designated as 10" and 11. The handle 11, for example, is provided with a slotted arm 12, which is returned between the two handles 10 and 11, as isbest shown in Fig. 1, and in the slotted portion of the return arm 12 a knife-blade 13 is pivoted, which knife is a powder-knife and is used in cutting giant-powder sticks or for similar purposes. This. arm, extending inwardly from the end of the curved handle, thus forms a support for the knife-blade, and the necessity for weakening the handle proper by recessing it to receive the blade is avoided and the knife-blade is held between the handle and out of the way. The construction shown is thus especially designed for use with a tool having curved handles. The pivot-pin 14, which is passed through both of the jaws, is provided at one of its ends with an attached socket 15, adapted to hold a candle. This socket, which is at one side of the tool, is perpendicular when the tool is in use, and the socket 15 is preferably made from a sheet of spring metal, one side of which is attached to the pivot, the other side being unattached, and the unattached portion of the socket is usually provided with a thumb-piece 16 in order that the diameter of the socket may be increased by pressing against the thu mb-piece when a candle is to be introduced into the socket, as shown in Figs. 1 and 3.

A hook 17 is preferably attached to or loosely mounted upon the pivot-pin let at the opposite side of the tool, and by means of the hook 17 the said tool may be suspended from a convenient support or may be attached to the clothing of the miner, and a pointed arm or a spike 18 is made integral with or is attached to one of the jaws of the tool, usually the jaw 10. This pointed arm or spike is utilized to fasten the tool to a wooden beam or to secure the tool in a seam of a rock.

In the inner face of the jaw 11 three semicircular recesses are made, (designated, respectively, as 19, 20, and 21.) At one end of the outer recess 21 one or more spurs 22 are formed, and a knife-blade 23 is made to extend across an end portion of the recess 20, the knife 23 and the spurs 22 being preferably located at the right-hand side of the jaw. A blade 2a is secured to the inner face of the jaw 10 in such position that the said blade, when the jaws are brought together, will enter the recess 19 in the jaw 11. The blade 24 constitutes a fuse-splitter and will split the fuse to admit of spitting it with powder before lighting. Y

ICO

Two semicircular recesses 25 and 27 are made in the inner face of the jaw 10, which recesses are adapted to register with the re cesses and 21 in the jaw 11.- A knife 26 extends across the right-hand end of the re cess 25, while one or more spurs 28 are formed at the right-hand end portion of the outer recess 27, the spurs 28 being adapted to register with the spurs 22 on the opposing jaw. The spurs 22 and 28 serve as crimpers to fasten the cap on the fuse. The knives 23 and 26 are arranged to pass one over the other and thereby produce a clean shearing out, while the recesses across which the knives are carried will prevent the fuse from becoming unduly crushed. The knives 23 and 26 are preferably made removable, so that they may be readily sharpened when they become dull, and to that end, as shown in Fig. 2, the knives are substantially dovetail shape in cross-section and are made to enter dovetail recesses 29, which are made in the right-hand side of the jaws 10 and 11.

It is evident that any one of the various appliances combined in the tool may be used as required and that the candle may at all times be held in avertical position.

Having thus described myinvention,I claim as new and desire to secure by Letters Patent 1. A tool for miners use, comprising pivotalIy-connected jaws provided with handles, the handle of one jaw being provided with a slotted arm returned between the two handles, and a knife-blade pivoted in the slotted portion of the return arm, the said jaws being equipped for treating a fuse, as and for the purpose set forth.

2. A tool for miners use, consisting of pivotally connected jaws provided with handles, one of said handles having a slotted arm extending inward between the handles, a knifeblade pivoted in the said slotted arm, the said jaws being equipped for treating a fuse, and one of said jaws having a sharp extension from its forward end adapted to enter a support substantially as specified.

3. A tool for miners use, comprising pivotally-connected jaws provided with handles, the handle of one jaw being provided with a slotted arm returned between the two handles, and a knife-blade pivoted in theslotted portion of the return arm, the said jaws being equipped for treating a fuse, the said tool being provided with a socket adapted to receive a candle, and means for securing the tool to a support, substantially as shown and described. v
